To (iZZ- whom it may concern:

Be it known tr t 1. JOHN L; lav-Non, a citizen of the illlnited States, residingat Starbuck, in the county of Pope and State of 'lviinnesota, have invented certain new and IISQ'i Ltl lmprdvei'nents in Crates, of which the following is a specification.

The present invention relates to an improved crate.

Difficulty is experienced in the manufacture of egg crates in securing a cover therefor which is inexpensive and which may be readily and securely fastened in place-but shall be easily removed when it is desired to fill or unload the crate.

An object of the present invention is to make an egg crate with an improved type of cover fastening therefor.

Another objectis to make an inexpensive and durable interlocking fastening for an egg crate cover.

In order to attain these 0bjects, there is provided in accordance with one feature of the invention, perforated lugs fastened to a side of a crate, and a perforated spring fastened to an opposite side thereof. Projecting lugs are fastened to a cover for the crate to engage the perforated lugs, and a lug which may be slightly longer than those which engage the perforated lugs is connected to the cover in a position to engage the perforated spring when the cover is in position on the crate.

These and other features of the invention not specifically mentioned will be more fully brought out in the following description and the accompanying drawings, wherein similar referencecharacters are used to denote the same parts throughout the various views. Referring to the drawings: 7

member with a portion of'the crate body and top therefor, tl'ieportion of the cratebody beingshown in 'dottedlines so as topermit theillustration ofthe lug connected thereto,

Referring to the drawings in detail, a crate A may be built up of boards in a well known manner and lugs 1 are fastened to one side thereof as by means of screws. Each lug l is perforated at 2, the bottom of the fastened a spring member 3, the bottom of which is preferably at a height above the top of the top edge of the crate equal to the thickness of a cover to be used therewith.

A crate cover B which may be built of boards secured together by means of cleats t in a well known manner, has secured there to at points to register with the perforations in lugs 1, metal members 5, a nose portion 6 of which extends over the edge of the cover in a manner to engage the perforations in the lugs 1 when the cover is in position. A third metal member 7 may be secured to the cover by means of screws and this member is preferably provided with an elongated nose 8 having a perforation 9 therein. Spring member 3 is positioned to engage the nose 8 with the perforation therein. A pin 10 of a size to enter the perforation 9 in the nose of member 7 may be connected to the body of the box as'by means of a chain and staple 11. I

In placing a cover B in position, the noses of metal members 5 are first introduced into the perforations in lugs 1, and the opposite side of the cover is then brought down so that the nose of metal member engages the curved upper portion of spring member 3 moving it outward until the perforation therein registers with the nose of member 7 whereon the spring 3 snaps securely in engaging member 7, thereby locking the cover securely in place. To prevent displacement of the spring 3 from contact with member 7 during transit, the pin 10 may be inserted in perforation 9*in metal member 7. To prevent lateral moving of the cover in thedirection of spring member 3 to move metal members 5 from engagement with the perforations in lugs 1, the cleats 4 may ex tend to withina short distanceof the side of the crate to which is connected spring member 3.

The operation of the cover fastening illustrated in Figure 6 is similar to that shown in Figure 1, and Will be apparent from the illustration and the foregoing description of the type shown in Figure 1.

hat I claim is:

1. In an egg crate, a cover fastening, comprising perforated lugs connected to the body of an egg crate, a perforated spring connected to the opposite side of the body thereof, lugs to register with and engage the perforated lugs connected to the body of the crate and to rcmovably look a cover on an egg crate.

2. In an egg crate, a cover fastening, comprising indented members connected to the sides of the crate, projecting members interlockingly engaging said lugs, a springmember connected to a side of the crate other than that to which the lugs are connected, a projecting member interlockingly engaging said spring member upon seating the cover, and means connected interior of the cover to'prevent lateral displacement thereof.

In testimony whereof I aifix my signature.

JOHN 'L. LYNCH.
